Russia’s Aeroflot plane has been searched by the British authorities at London’s Heathrow airport, no reasons were given, an Aeroflot source told TASS on Friday.

"The British side provided no grounds for a plane search," the source said.

"It was decided that after the British side finishes the search, the plane will be additionally examined by the crew and the company’s office employees as the British side compelled the crew to leave the plane during the search."
